Changing Facebook’s identity didn’t smooth as they thought, there was someone already in front of facebook trying to get the “meta” trademark and they’re trying to give it up to Zuckerberg at a high price.

In August, the founder of a company called Meta PC filed for trademark registration of the word “meta” for computers, laptops, tablets, software, and other items related to technology.

Mark Zuckerberg may have to buy Meta’s trademark for $ 20 million after a computer retailer claims to have defeated Facebook’s founder with a trademark.

Arizona-based MetaPC introduced the “Meta” trademark on computers, laptops, tablets, software, and other tech-related items on August 23, not far from the Silicon Valley giant market. ..

Founders Joe Darger and Zuck Shut told that they were ready to withdraw the brand name if Zuckerberg agreed to pay $20 million.

The tech expert says they have been running the company for over a year and has invested “significant personal money” in meta marketing and branding.

But not all share names are bad, as they have revealed that social media pages have already grown by 5,000% since Zuckerberg’s announcement on Meta.

A Meta (Facebook) source told that the company believes it has the right to adopt the brand.

Sometimes we may try our design horizontal or 90 degree for a bit more interesting layout. If you want to do that, Flutter has answered. Just use RotatedBox.

RotatedBox has provided a child and a number of quarter turns you want to rotate. One quarter to 90 degree turns.

So,

If we set 1 quarter, that will turn to 90 degree.

If we set 2 quarter, that will turn to 180 degree

If we set 3 quarter, that will turn to 270 degree

If we set 4 quarter, that will turn to 360 degree.

If we use 5 quarter, that will turn to 90 degree again.

RotatedBox(
quarterTurns : 3,
child: MyWidget(),
)

Let’s build example with RotatedBox.

Firstly, add assets image to pubspec.yaml file. After adding image assets, run flutter pub get.

assets:
  - assets/

Second step is in your main.dart file, that’s need to create a rotated box. Inside a RotatedBox() widget, we will call quarterTurns and a child.

Inside a child, we will add inside a ClipPath and his child’s property with image. The result will be underneath screen capture.

Example code :

return Scaffold(
  backgroundColor: Colors.grey[100],
  appBar: AppBar(
    title: const Text("Rotated Box"),
    backgroundColor: Colors.blueGrey[800],

  ),
  body: const Center(
      child: RotatedBox(
          quarterTurns: 5,
          child: ClipPath(
              child: Image(
                image: AssetImage("assets/logo.png"),
                fit: BoxFit.contain,
                height: 200,

              )

          )
      )
  ),
);

For this week, I would like to share about cropping the bulk images with the same dimensions in python. This method is useful in some cases that image processing or some steps of computer vision projects. The following python script is to crop all images in a folder and save the result to another folder. I used Pillow image library to crop images.

Note: All images to be cropped must be the same dimensions.

First, import required libraries.

import os
import glob  # pip install glob2
from PIL import Image  # pip install Pillow
from pyfiglet import Figlet  # pip install pyfiglet

---

Program flow is to ask user for the bulk image directory path , desired output directory path and coordinates to be cropped. Then crop all images and save the result to output directory.

def main():
        getDirandFiletype()
        getCoordinate()
        for x in filenames:
            name = x.replace(img_dir, '')
            img = Image.open(str(x))
            region = img.crop((left, top,right, bottom))
            region.save(outpath + name)
        print(custom_fig.renderText('Done!'))

---

Then in getDirandFiletype() function, the user is asked for image path and output path and read all files in the path with the help of glob library. And also show dimension of each image to be cropped.

def getDirandFiletype():
        global img_dir, outpath, filenames

        print("Please enter Your Images Path.  eg:D:\Download\jaffedbase\n\n########################################")
        img_dir = input("\nWhat is your image directory path : ")
        outpath = input("\nWhat is your output path where to be saved : ")
        
        while(outpath == img_dir):
            print('\nEnter a different path with the image directory!!')
            outpath = input("\nWhat is your output path where to be saved : ")

        filetype = input("\nEnter file type (eg: png) : ")
        data_path = os.path.join(img_dir)
        # read all files in the path mentioned
        filenames = glob.glob(data_path + "/*." + filetype)
        processed = 0
        for file in filenames:
            img = Image.open(str(file))
            width, height = img.size
            print("\nDimension of source images : "+str(width),str(height))
            processed += 1
            if processed >= 1:
                break 

---

And in getCoordinate() function, the user is asked for the cropping area with left, top, right, bottom coordinates. Pillow image library is used for cropping.

def getCoordinate():
        global left, top, right, bottom, img
        left = int(input("\nEnter left coordinate : "))  
        top = int(input("Enter top coordinate : "))  
        right = int(input("Enter right coordinate : "))  
        bottom = int(input("Enter bottom coordinate : ")) 

---

That is all. The final code with error handling and beautiful text render with pyfliglet library is as follows.

import os
import glob  # pip install glob2
from PIL import Image  # pip install Pillow
from pyfiglet import Figlet  # pip install pyfiglet

try:
    custom_fig = Figlet(font='standard')
    def main():
        getDirandFiletype()
        getCoordinate()
        for x in filenames:
            name = x.replace(img_dir, '')
            img = Image.open(str(x))
            region = img.crop((left, top,right, bottom))
            region.save(outpath + name)
        print(custom_fig.renderText('Done!'))
        
    def getDirandFiletype():
        global img_dir, outpath, filenames

        print("Please enter Your Images Path.  eg:D:\Download\jaffedbase\n\n########################################")
        img_dir = input("\nWhat is your image directory path : ")
        outpath = input("\nWhat is your output path where to be saved : ")
        
        while(outpath == img_dir):
            print('\nEnter a different path with the image directory!!')
            outpath = input("\nWhat is your output path where to be saved : ")

        filetype = input("\nEnter file type (eg: png) : ")
        data_path = os.path.join(img_dir)
        # read all files in the path mentioned
        filenames = glob.glob(data_path + "/*." + filetype)
        processed = 0
        for file in filenames:
            img = Image.open(str(file))
            width, height = img.size
            print("\nDimension of source images : "+str(width),str(height))
            processed += 1
            if processed >= 1:
                break 
            
    def getCoordinate():
        global left, top, right, bottom, img
        left = int(input("\nEnter left coordinate : "))  # 50
        top = int(input("Enter top coordinate : "))  # 50
        right = int(input("Enter right coordinate : "))  # 190
        bottom = int(input("Enter bottom coordinate : "))  # 235
    
    
    main()
except SystemError:
    print("\nSorry Buddy. Your Coordinates are invalid. Plese Check Coordinates Again!")
except ValueError:
    print("\nPlease use Only Numbers for Coordinates!")

Images to be cropped are as follows.

The resulted images are as follows.

Hope you enjoyed about this.
